Frequently Asked Questions

Alloy steels are steels alloyed with elements such as chromium, nickel, molybdenum, or vanadium to improve mechanical properties and performance.

Alloy steels are used in aerospace structures, pressure vessels, pipelines, tools, and machinery requiring high strength and toughness.

Alloy steel differs from carbon steel by the addition of alloying elements like chromium, nickel, and molybdenum to improve mechanical properties and corrosion resistance.

Types include low-alloy steel (up to 8% alloying elements) and high-alloy steel (above 8%), tailored for strength, wear resistance, or toughness.

Commonly added elements include chromium, nickel, molybdenum, vanadium, manganese, silicon, and boron to enhance strength, hardness, and corrosion resistance.

Non-Ferrous

Non-ferrous alloys are, literally, materials that are not iron-based. While others may provide non-ferrous materials of other materials, the MetalTek family of non-ferrous alloys are copper-based. In general, these materials deliver high strength, and excellent wear and corrosion resistance. They are often found in marine applications and also bushing, bearing, and gear environments.
Stainless Steel Parts

Stainless Steel

Stainless steels owe their ability to resist corrosion primarily to the presence of a passive film on their surface. Chromium is chiefly responsible for formation of the passive film. Iron ceases to rust at approximately 12% chromium content and resistance to oxidizing corrosives increases rapidly with chromium content up to approximately 20%.
Petrochemical Fittings

Specialty Alloys

Specialty Alloys comprise a broad group of materials that deliver properties for more demanding applications, use more exotic or expensive materials, or require special processes to manufacture. Where standard materials may not offer desired performance, specialty alloys (including those that are modified further) may be a sensible selection.
